So accustomed are we to metaphors related to taste that when we hear a kind smile described as “sweet,” or a resentful comment as “bitter,” we most likely don’t even think of those words as metaphors. But while it may seem to our ears that “sweet” by any other name means the same thing, new research shows that taste-related words actually engage the emotional centers of the brain more than literal words with the same meaning.

Researchers from Princeton University and the Free University of Berlin report in the Journal of Cognitive Neuroscience the first study to experimentally show that the brain processes these everyday metaphors differently than literal language. In the study, participants read 37 sentences that included common metaphors based on taste while the researchers recorded their brain activity. Each taste-related word was then swapped with a literal counterpart so that, for instance, “She looked at him sweetly” became “She looked at him kindly.”

Researchers from Princeton University and the Free University of Berlin found that taste-related metaphors such as “sweet” actually engage the emotional centers of the brain more than literal words such as “kind” that have the same meaning. If metaphors in general elicit a similar emotional response, that could mean that figurative language presents a “rhetorical advantage” when communicating with others.

3810233454_10cbc36346Every day it seems like we feel hundreds of different emotions – each nuanced and specific to the physical and social situations we find ourselves in.

According to science, it’s not that complicated by a long shot. A new study says we’re really only capable of four “basic” emotions: happy, sad, afraid/surprised, and angry/disgusted.

But much like the “mother sauces” of cooking allow you to make pretty much any kind of food under the sun, these four “mother emotions” meld together in myriad ways in our brains to create our layered emotional stews.

Robert Plutchik’s famous “wheel of emotions” shows just some of the well known emotional layers.

In this post we’ll take a close look at each of the four emotions, how they form in the brain and the way they can motivate us to surprising actions. Read More

ASK a person to describe themself, and they will probably recite a list of their physical features — their height, weight, the color of their skin, hair, and eyes. If they’re more a more externalized type, they might mention their job, sexuality, religion, or a major life achievement. Some might feel a desire to be precise and catalog their external features: their eyes, face, arms, hands, legs, feet, fingers, and toes for you.

Few will ever mention their brain.

Why Your Mind Will Never Be Uploadable.

The rise of computing and the exponential rate of increase in processing speed pose an intriguing questions for scientists; what happens when computers become smarter than their human masters — the so-called “Technological Singularity”. Will machines take over? Would they turn on humans and destroy us? Will we increasingly integrate computing modules into our bodies to cure disease or enhance our natural abilities? What effect does all of this technology have on issues of equality and power among the various members of the human race?

One of the popular philosophies attached to this futurist realm is the idea of transcendence (now a major motion picture!). That is, the concept that a person’s mind could be digitally uploaded to a computer, thus “transcending” the limitations of the biological body to acquire immortality. It’s a relatively widespread idea that has been written about extensively in popular science literature, even making a cameo in an episode of “The Big Bang Theory”. It is also a major theme for followers of Transhumanist philosophy. As the world focuses more and more on the implications of our technological development, transcendence is becoming one of those concepts in popular science that are so widely-known that they become accepted as inevitable, regardless of the state of current scientific knowledge regarding their actual feasibility. Fortunately, no one reading this in the early 21st Century will achieve immortality by uploading their mind to Amazon. Read More

Pediatric neurologist Michelle Monje led the team that became the first to create an animal model of a rare, fatal brain tumor that strikes young children.

A pediatric brain tumor that causes gruesome suffering is finally yielding its secrets. For the first time, scientists at the Stanford University School of Medicine have cultured human cells from this cancer, Diffuse Intrinsic Pontine Glioma, and used those cells to create an animal model of the disease. Their discoveries will facilitate research on new treatments for DIPG, a tumor of school-aged children that is now almost universally fatal. Read More
